All the statistic data are analyzed by KPS (Kernel Patch Statistic). In following table, "Employers" column shows varied types of organizations (including commercial companies, consultants, hobbyists, adademics and unknown type) contributed how much effort to Linux Kernel. And "Engineers" column shows engineers contribution rank. If you want to know the development trend during kernel development cycles, you can check the above link "Graphic Kernel Evolvement".
